Parts are in perfect shape. 

All three instruction manuals in good used shape. They were used once to build the set, so there is some wear, but they have been stored back in the box since.

Box is in decent shape. I am not sure if the front printing is slightly faded, or if that is just the style of the design. Edges and corners have some soft spots, and there are a few creases on a few corners as well. I would grade it as a B-. It still displays well though. I can send pics if requested.
